Creative Assembly has released the first official Total War modding tool, called simply "The Editor" (or TEd by the series' fans), which is automatically installed when gamers update Total War: Shogun 2 or Fall of the Samurai on Steam.

Sega has announced that the Dragon War Battle Pack is now available for Total War: Shogun 2. The DLC, which was previously only available for Total War: Shogun 2 - Fall of the Samurai, features the campaign of Saigo Takamori.
